NIST SP 800-82 (Special Publication 800-82) is a cybersecurity framework developed by the National Institute of Standards and Technology (NIST) in the United States. It provides guidance on how to secure industrial control systems (ICS), which are used in critical infrastructure sectors like energy, water, transportation, and manufacturing.

The latest version of NIST SP 800-82 is Revision 3 (draft), which introduces several important updates and improvements compared to the previous version. Here are some engaging and simplified points highlighting the key differences:

  • The Coverage

    Expanded Scope: NIST SP 800-82 Revision 3 (Draft) broadens the scope of the framework to cover not only traditional ICS but also emerging technologies like the Industrial Internet of Things (IIoT) and some other systems such as Building Automation Systems (BAS), Physical Access Control Systems (PACS), etc. The term that is being used also changed, from Industrial Control System (ICS) to Operational Technology (OT) covers broader systems including ICS as one of the main entities. This acknowledges the evolving threat landscape and the need for enhanced security measures.

    • The Risk

    Risk Management: The new version emphasizes a risk-based approach to cybersecurity. It introduces the concept of risk management frameworks, which help organizations identify and prioritize potential threats and vulnerabilities. This approach enables more targeted and effective security measures.

    • The Integration

    Integration with Cybersecurity Framework (CSF): NIST SP 800-82 Revision 3 (Draft) aligns with the NIST Cybersecurity Framework (CSF), providing a cohesive approach to managing cybersecurity across an organization. This integration allows organizations to leverage existing CSF practices and frameworks to secure their OT environments.

    • The Response Plan

    Enhanced Incident Response (IR): The latest version places greater emphasis on incident response and recovery. It provides detailed guidance on developing and implementing robust incident response plans specific to OT environments. This helps organizations minimize the impact of cybersecurity incidents and restore operations quickly.

    • The Supply Chain

    Supply Chain Security: NIST SP 800-82 Revision 3 (Draft) recognizes the importance of securing the supply chain, particularly for OT environments. It provides guidance on assessing and managing risks associated with third-party suppliers, ensuring that the software and hardware components used in OT systems are trustworthy and free from vulnerabilities.

    • The Access

    Access Control and Authentication: The new version emphasizes the importance of access control and strong authentication mechanisms. It provides guidance on implementing multi-factor authentication, password management, and user access controls. These measures help prevent unauthorized access and enhance the overall security posture.

    • The Threat

    Threat Intelligence and Monitoring: NIST SP 800-82 Revision 3 (Draft) emphasizes the need for continuous monitoring and threat intelligence. It provides guidance on implementing security controls and tools to detect and respond to potential threats in real-time. This proactive approach enables organizations to stay ahead of emerging threats.

    • The Controls

    New tailoring guidance for NIST SP 800-53, Rev. 5 security controls with an OT overlay that provides mapped security control baselines for low-impact, moderate-impact, and high-impact OT systems.

    • The Program

    Cybersecurity Program: Reference to ISA-62443-2-1 standard for the cybersecurity program to be used in the OT environment. Some guidelines on how to fulfil the cybersecurity requirements are described for each element of the cybersecurity program.

    In summary, NIST SP 800-82 Revision 3 represents an enhanced and more comprehensive framework for securing industrial control systems. It incorporates a risk-based approach, aligns with the NIST Cybersecurity Framework, and addresses emerging technologies and supply chain security. By focusing on incident response, access control, and continuous monitoring, organizations can better protect their critical infrastructure from cyber threats.
